try giving Claire a call, she willo do shared load down. One of my liveries horses came down from Cheshire to here with her and he treavelled really well.
Look at www.horsetransportnetwork.com. If you fill out the form with your details several transporters will send you quotes. I have used this method several times and found it very good.
Try Alan Walters - 01984 623624. He is always up and down country specially if you can get in on a load already coming back after racing! - Worth a try!
1 email to go out to all the licensed transporters on there
You will need to say that you are on a budget but seriously with the diesel price hitting the 1.40 per litre barrier the transporters have no option but to pass cost on
The cheapest by far would be for YOU to self drive and hire a box
